Physics Stage 6 – Yr 12 Notes 9.2 Space: Context 1 – The Earth has a gravitational field that exerts a force on objects both on it and around it. Define weight as the force on an object due to a gravitational field Mass (m): • The amount of matter in a body • Constant anywhere in the universe • Scalar quantity • Measured in Kilograms (Kg) Weight (W): • The force acting on an object due to a gravitational field • Attractive force • Vector quantity

through a more advanced explanation. Roller coaster rides involve a great deal of physics. The ride often begins with a chain and motor which exerts a force on the train of cars to lift the train to the top of a tall hill. Once the cars are lifted to the top of the hill‚ gravity takes over and the rest of the ride works on energy transformation. There is no motor or engine that takes a train around the track. The law of physics is basically the engine of the train. At the top of the hill‚ the cars possess

AP10005 Physics I Tutorial 7 (Chapters 17‚ 18) 1. (17P11) A flower pot is knocked off a window ledge from a height d = 20.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h =1.75 m who is standing below. Assume the man requires a time interval of Δt = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? 2. (17P15)

The physics of scuba diving Imagine swimming in the underwater world with all the creatures and all the beauty it holds. It is an amazing feeling to swim over coral reefs and see all the sea life up close and personal. So many scuba divers all over the world share a passion to scuba dive. Scuba diving has been a worldwide endeavor for centuries (1). Persian divers were making goggles for diving around 1300. A British engineer invented the air pump in 1771 and in 1772 a Frenchman tried inventing

Year 12 Physics 2014 ER – The Physics of Medicine Extended Response Task [Type the author name] This report will discuss how cerebrovascular disease‚ in particular ischemic stroke‚ can be diagnosed using magnetic resonance imaging scans. It will go through the different MRI sequences and the physics behind them. Evidence from two case studies are presented‚ which use the MRI sequences discussed within this report. Consequently‚ the recent advances in diagnostic techniques and methodologies will

“Cartoon Physics‚ Part 1” Nick Flynn centers “Cartoon Physics‚ Part 1” around childhood innocence. He very strongly urges not only parents‚ but anyone around a young child to not force upon them knowledge they do not need to know. Flynn captures the simple kid mind and harsh reality with tone‚ imagery‚ figurative language‚ and even the form of the overall poem. There is a stark contrast between tones in the passage. In the first few lines the tone is cold; detached. The actual physics of the never-ending

ours‚ our findings can hardly pale into insignificance as errors and the cause of uncertainty are discussed and ways to improve the experiment are suggested‚ which can possibly spur further studies on this realm of knowledge. I. Introduction In physics‚ there are mainly two ways from which useful equations can be derived. One from them is to make good use of the mathematical expression of the theories formulated by our predecessors. An archetype to this notion is the Newton’s second law‚ which states

he was many things)—an author‚ printer‚ politician‚ scientist‚ musician‚ inventor‚ and much‚ much more. He made significant contributions to many fields. However‚ he is probably best known for his work in science‚ especially in electricity and the physics of electricity. For the areas of science in which he worked‚ he is known for his studies in the theory of electricity and his useful inventions. These include the Franklin stove‚ bifocal eyeglasses‚ the lightning rod‚ and daylight savings time. One
